The listing, Slurpee Nation Promo Cup Rewards Code (5 Points) has ended.
I have a Slurpee Nation Rewards Code from a Promo Cup worth 5 points that I don't plan to use myself. I will message the auction winner with the code.
You have to be or become a Slurpee Nation Rewards Code Member. It's free to become a member and start collecting points.
Looking at the website (I guess you have to copy/paste the url. I couldn't get it to be a clickable link),
http://slurpee.com/Rewards/ViewItemType.aspx?sItemType=Products&sCategory=All
in my opinion the coolest thing I found you could get with the 5 points is one RedBox rental which is worth one dollar. Of course, you can collect points and redeem them for other stuff like T-shirts and stuff.
